A wild cat with spots, native to the woods of Bolivia, has been established as a distinct species, and the full body of science about South American wild cats could now require revision. The report, published in Current Biology, expands the tiger cat genus to five species, with the new species known from just one surviving specimen.
The Cat That Started It All
A small feline, roughly the size of a domestic moggy, was overlooked for years due to its resemblance to other wild cats that carry similar spots and stripes. DNA research has since confirmed that the cat stands apart from those others, a finding that underscores how much we still don’t know about some of the world’s most elusive mammals.
A local resident came across what appeared to be a young domestic kitten while walking through the forest in Bolivia. The animal was eventually taken into a rescue sanctuary, where it has remained ever since. As the cat aged, its behavior diverged from that of ordinary house cats, and it has now been identified as the sole confirmed member of its species, a 10-year-old cat.
How the Cat Was Found
Paola Nogales-Ascarrunz, a Bolivian scientist, spotted something odd while working as a volunteer at the sanctuary. Other people had reported seeing small wild cats in the thick forests of the country’s Yungas region, though none of those accounts had been examined by researchers.
In her quest for answers, she collaborated with investigators from across the globe to trace the ancestry of tiger cats through DNA taken from both living creatures and museum specimens. The research turned up additional surprises, pointing to five tiger cat species instead of three, with the newly identified Tilcaya cat (Leopardus tilcayo) of Bolivia among them.
What Is a Tiger Cat?
Across Central and South America, from Costa Rica to Bolivia and Argentina, tiger cats roam. These small, spotted wild cats are so alike in appearance that even experts often find it difficult to distinguish between them.
The new species is named Leopardus tilcayo.
The DNA Evidence
“There’s so few records or pictures, no individual in a museum, so it was hiding because nobody was looking,” said Eduardo Eizirik, a conservation geneticist at the Pontifical Catholic University of Rio Grande do Sul in Brazil.
Genetic research was crucial in establishing the new species. By comparing DNA from live animals with that of preserved specimens, scientists constructed a family tree. That analysis revealed the Bolivian cat sits within its own distinct branch, separate from all previously recognized species.
Why This Matters for Conservation
Conservation depends on knowing what a species is and where it lives, and without that knowledge, protecting it becomes impossible.
“These are animals similar in size to a domestic cat, so you might think we would know them all by now, but this discovery shows how much biodiversity is still to be uncovered in some of the less-studied regions of the world,” said Co-researcher Dr Caroline Sartor, of the Wildlife Conservation Research Unit at the University of Oxford.
Vulnerable to Extinction
Tiger cat species face a high risk of extinction due to deforestation, habitat loss and poaching. The new species was not included in earlier assessments, so its population status had not been determined prior to this study.
The Taxonomic Nightmare
According to Andrew Kitchener, an expert in mammals at National Museums, Scotland, who was not involved with the research, the small spotted South American cats known as tiger cats have been a “taxonomic nightmare” for years.
“These cats are confusing because they look so similar and there are few specimens in museums, so even now we are still learning how to tell them apart as genetics reveal more species,” he said.
| Feature | Leopardus tilcayo | Other tiger cats |
|---|---|---|
| Known individuals | One living specimen | Widespread across range |
| Habitat | Yungas forests, Bolivia | Across Central and South America |
| Status | New species | Vulnerable to extinction |
What Comes Next
The identification of the species marks just the beginning of what scientists suspect may be many more discoveries in the Yungas forests. The research team believes additional species remain to be found there. They hope the current discovery will bring greater notice to the conservation of tiger cats, a collection of small wild felines that have received far less public attention than their larger cousins, including lions, leopards and tigers.
This find raises the total count of recognised felid species to 44 or more. Wild cats and household companions both sit within the biological family Felidae, a group that encompasses every living cat species, from small house pets up to large tigers. The official tally stands at 41, though the new discovery, along with evidence that there could be several species of tiger cat, sends that figure upward.
The Amazing Result
“It’s an amazing result that we have a new species for the world, which is the Leopardus tilcayo,” said Paola Nogales-Ascarrunz of Universidad Mayor de San Andres in La Paz, Bolivia.
“It’s amazing that there are still new species waiting to be discovered: we don’t have to go to a volcano, an island, or deep into the sea.”
Finding a new species is unusual, yet it occurs. What stands out is that this creature was living right under everyone’s nose — a strange-looking cat at a rescue sanctuary that nobody could identify. It took DNA evidence to prove its true nature, and now science has added one more wild cat to the Earth’s count.
A lone rescued cat has reshaped what researchers understand about South American wild felines. It serves as proof that the natural world continues to conceal its mysteries, and that one creature, when brought into the proper care, can entirely recast a portion of zoological knowledge.
